WordPress Troubleshooting – Fast Fix for Error 500, WSOD & PHP Conflicts

White screen after an update? Error 500 popping up at checkout? I locate the conflict, repair the code, and get your site back online—usually in under an hour, any time of day.

Common WordPress Errors I Solve Daily

• White Screen of Death (WSOD) after plugin update
• Internal Server Error 500 – .htaccess or PHP limit
• Memory exhausted / fatal error in functions.php
• Conflict between page-builder and WooCommerce
• Database connection lost after host migration
• Media library thumbnails not generating
• REST API or AJAX returning 403
• Checkout page blank or looping

My Diagnostic Workflow

1. 1. Immediate backup – files + database snapshot
2. 2. Enable WP_DEBUG – capture real PHP messages
3. 3. Health Check – deactivate plugins/themes in sandbox
4. 4. Log analysis – Apache/Nginx + PHP-FPM
5. 5. Conflict isolation – binary search through mu-plugins
6. 6. Patch & test – code fix or rollback, then re-activate

Tools & Access Required

• SSH / SFTP credentials or hosting panel
• phpMyAdmin or direct MySQL access
• WP-CLI pre-installed (I can add it if missing)
• Git repo (optional) for versioned rollback

When to Call a Professional

• Site down > 30 min and host support blames your code
• Checkout broken during high-season sale
• You already tried disabling plugins without luck
• Error appears only on mobile or specific user role
• Multilingual setup (WPML/Polylang) involved

Pre-Support Checklist (Speeds Up Repair)

• Note exact time the error first appeared
• List last 3 changes (plugin update, new theme, host switch)
• Grab screenshot of browser console (F12)
• Export last 100 lines of error log from hosting panel
• Confirm PHP version and memory_limit value

Quick FAQ

Do you offer a warranty?

14-day free re-fix if the same root cause re-appears.

Will my SEO be affected?

Downtime is minimized (<1 h) and I resubmit sitemap to Search Console immediately.
